Dear journal, 

I was once a living breathing pig. Now I am little more than a couple of vegetables, some grains and a few slices of meat. I sit on a plate waiting to be eaten by a hungry human. I am a happy sandwich, about to go through an exciting journey called the digestive system.

I begin my journey at the mouth, the site of ingestion. I am being eaten. The teeth bite me into small pieces and are responsible for physical digestion. They increase my surface area. Once in the mouth I encounter the tongue. I am being tasted and being moved around in the mouth. Salivary Glands produce saliva,  dome which contains mucus and amylase. The saliva starts chemical digestion which breaks me down.
